The 50 State Quarters Program, which ran from 1999 to 2008, remains a landmark series for coin collectors. While most of these coins are common, a select few have become highly valuable due to minting errors and anomalies. These rare coins capture collectors’ attention, with some fetching over $1 million at auction.
Let’s dive into the most valuable state quarters and what makes them so sought after.
The Five Most Valuable State Quarters
These coins have earned their place as collector favorites due to unique errors, design anomalies, and limited availability.
1. Delaware Quarter: The “Spitting Horse” Error (1999)
The Delaware quarter features a design of Caesar Rodney riding a horse. A rare minting error caused a die crack to create the illusion of the horse “spitting.” This anomaly, nicknamed the “Spitting Horse”, makes the coin incredibly rare and collectible.
- Auction Value: Over $1 million in pristine condition.
2. Minnesota Quarter: The “Extra Tree” Error (2005)
The Minnesota quarter’s forest design is altered by a minting inconsistency that adds an “extra tree” to the scene. This error is subtle but highly desirable among collectors.
- Auction Value: Over $1 million for flawless examples.
3. Wisconsin Quarter: High Leaf and Low Leaf Varieties (2004)
This quarter features a corn stalk design where additional leaves appear due to die gouges. The “High Leaf” and “Low Leaf” varieties are rare and highly valued.
- Auction Value: Exceeds $1 million in top condition.
4. Georgia Quarter: Doubled Leaves Error (1999)
The Georgia quarter features a peach surrounded by leaves. In some cases, a minting error causes the leaves to appear doubled. This subtle but distinct mistake makes the coin a prized find.
- Auction Value: Over $1 million for top-grade coins.
5. Kansas Quarter: The “In God We Rust” Error (2005)
The Kansas quarter is infamous for a grease-filled die error that caused the “T” in “Trust” to appear faint or missing, resulting in the phrase “In God We Rust.” This unique flaw has become highly collectible.
- Auction Value: More than $1 million at auction for well-preserved examples.

Though these coins don’t reach million-dollar valuations, they remain a part of the thriving collector’s market.
What Makes State Quarters Valuable?
State quarters achieve high value based on these factors:
- Minting Errors
Coins with errors like die cracks, doubled designs, or grease-filled inscriptions are especially desirable due to their rarity. - Rarity
Low mintage numbers or limited production runs drive up demand among collectors. - Condition
Coins in pristine, uncirculated condition (graded as MS-65 or higher) command the highest prices at auction. - Historical and Sentimental Appeal
State quarters showcase U.S. history and culture, adding intrinsic value for collectors.
How to Identify Valuable State Quarters

- Wisconsin’s High/Low Leaf: Check the corn stalk for an extra leaf at the top or bottom.
- Georgia’s Doubled Leaves: Look for overlapping or repeated leaf patterns.
